Gildan Men Cotton Short Sleeve Black Crew T-Shirt, 4-Pack,

These t-shirts from Gildan are great - they have a lot going for them that I like. First the cut of the shirt - it is a modern / athletic / slim cut shirt. It doesn't have a ton of extra material around the mid section and I really like that. I'm 5'8", 160 pounds with a 42 chest and a 32 waist and these shirts are cut in a manner that don't hang and billow a bunch of excess shirt around my waist. The arms are also cut short so they will show off your arms. The length is good and helps them stay tucked in. The material is great too. The poly / cotton blend gives the fabric a little stretch and also helps keep you cool and dry. The colors are great and compliment most anything as an undershirt or are vibrant enough to wear alone. As far as sizing goes I'm constantly bouncing between a medium and a large depending on the cut of the shirt and how they are sized. The medium in these shirts are quite snug. I would put them at the smaller end of the "medium" sizing chart. That works great for an undershirt but for a stand alone t-shirt I prefer a large.
